WebbIf you truly want to check if two polygons share more than x number of points you can simply do this: p0,p1,p2 = polygons x = 2 len (set (p1.boundary.coords).intersection (p2.boundary.coords))>=x But I think what you may want is to determine if two edges are colinear (and overlapping).

If small 'cracks' appear where B was adjacent to C, maybe take a small buffer of the union before diffing.
